From QCD to Hadron Physics: Taking the Baby Steps

QCD makes the most challenging component of the Standard Theory of 
Particle Physics. It is a strong interaction, yet quarks are 
asymptotically free. It is unique in harboring the emergent 
phenomena of dynamical mass generation and confinement of colored 
excitations. It is also astonishingly peculiar in that the 
fundamental degrees of freedom which enter the Lagrangian are not 
accessible in the detectors. We cannot see quarks and gluons, yet 
they conspire to outpour a plethora of hadrons and account for 
most mass observed in the visible universe, outshining the Higgs 
mechanism almost completely. 

Can we aspire to explain the observable world of hadrons, their 
static and dynamic properties, starting from the QCD Lagrangian? 
The current status is that the detailed understanding of even the 
simplest of strongly interacting bound states has been 
non-trivially elusive to us. 

In this talk, I shall highlight some of the headway we have made 
in this direction within the formalism of its fundamental field 
theoretic equations of motion.
